PURPOSE: A soil retaining apparatus for the impact absorption of a falling rock defense wall is provided to maximize the supporting force of a falling rock defense wall by autonomously absorbing an impact load delivered from a falling rock or soil and blocking impact transmission to a support beam. CONSTITUTION: A soil retaining apparatus(100) for the impact absorption of a falling rock defense wall includes a base unit(110), a guide pin(120), an elastic member(130), and a moving body(140). The base unit is inserted into a support beam. The guide pin is installed to protrude to an opened front side on the base unit. The elastic member is elastically installed in the guide pin and absorbs impacts inputted from every side. The moving body is formed in a side closing the every side of the base unit, includes an accommodating space and an inclined projection(141), and moves to the inside of the base unit while compressing the elastic member by external force.
